View Data During Simulation

View data during simulation using Scope blocks, the Record block, or the Simulation Data Inspector

Scope blocks and scope viewers offer a quick way to visualize simulation data over time. If you are prototyping a model, connect signals to a Scope block, simulate the model, and then view the results in a scope window. Use the results to validate your design. If you need to debug your model, use oscilloscope-like tools in the Scope, such as triggers and cursor measurements, to locate the problem. To learn more, see Prototype and Debug Models with Scopes.
